<h2>
La Felicisima Armada
</h2>

<h3>Description</h3>

<p>The Spanish Armada (Spanish: <em>Grande y Felicisima Armada</em>, literally &quot;Great and Most Fortunate Navy&quot;) was a Spanish fleet of 130 ships 
that sailed from La Coruna in August 1588.
During its preparation, several accounts of its formidable strength
were circulated to reassure allied powers of Spain or to intimidate its enemies.
One such account was given by Paz Salas et Alvarez (1588).
The intent was bring the forces of Spain to invade England, overthrow
Queen Elizabeth I, and re-establish Spanish control of the Netherlands.
However the Armada
was not as fortunate as hoped: it was all destroyed in one week's fighting.

<p>de Falguerolles (2008) reports the table given here as <code>Armada</code>
as an early example of data to which multivariate methods might be applied.
